📍 Control Valves

🔎 What Are Control Valves?

Control valves regulate flow, pressure, temperature, or level of process fluids with precision.

They are widely used in power plants for steam control, petrochemical facilities for flow regulation, food & pharmaceutical industries for process safety, and water & wastewater plants for flow management.

Choosing the right control valve is critical for process safety, product quality, energy efficiency, and regulatory compliance.

🧭 Types of Control Valves

⚙️ Globe Valves

Principle: Linear motion disk regulates flow.
Applications: Steam, water, chemical processes
Example models:

Emerson Fisher Globe Control Valves
ABB Globe Valves
Yokogawa Globe Type Control Valves
Siemens Globe Valves

🔄 Ball Valves

Principle: Rotating ball regulates flow.
Applications: Gas pipelines, high‑pressure liquids
Example models:

Emerson Fisher Ball Valves
ABB Ball Control Valves
Yokogawa Ball Valves
Siemens Ball Valves

🦋 Butterfly Valves

Principle: Rotating disk regulates flow.
Applications: Large diameter pipelines, water and air systems
Example models:

Emerson Fisher Butterfly Valves
ABB Butterfly Valves
Yokogawa Butterfly Valves
Siemens Butterfly Valves

🩺 Diaphragm Valves

Principle: Flexible diaphragm regulates flow.
Applications: Corrosive liquids, hygienic processes (pharma, food)
Example models:

Emerson Diaphragm Valves
ABB Diaphragm Valves
Yokogawa Diaphragm Valves
Siemens Diaphragm Valves

🎛️ Positioners

Positioners optimize actuator signals to ensure the valve reaches the desired position.

Types:

Pneumatic positioners
Electronic positioners
Smart (digital) positioners

Example models:

Emerson Fisher FIELDVUE Positioners
ABB TZIDC Digital Positioner
Yokogawa YVP Positioners
Siemens SIPART PS2 Positioners

Positioners enable higher accuracy, faster response, and reliable valve performance.

Communication Protocols: HART, Profibus PA, Foundation Fieldbus, Profinet
SIL Compliance: SIL2/SIL3 certified versions are critical for ESD valves
Fail‑Safe Functions: Positioners integrated with actuators for safe shutdown scenarios

⚖️ Comparison of Control Valve Types

Type	Principle	Application Area	Strengths	Considerations
Globe	Linear disk	Steam, water, chemical	Precise control	High pressure drop
Ball	Rotating ball	Gas, high pressure	Tight shut‑off	Requires high torque
Butterfly	Rotating disk	Large pipelines	Lightweight, cost‑effective	Lower accuracy
Diaphragm	Flexible diaphragm	Corrosive, hygienic	Chemical resistance	Pressure limitations

🧠 How to Select the Right Control Valve

Selection criteria include:

Fluid type (water, steam, gas, chemical)
Pressure and temperature conditions
Pipe diameter and connection standard (ANSI, DIN, JIS)
Cv value and flow characteristics
Actuator type (electric, pneumatic, hydraulic)
Positioner requirement (for precise control)

Application examples:

Steam control → Emerson Fisher Globe Valves + FIELDVUE DVC6200 SIS
Gas pipelines → Siemens Ball Valves + SIPART PS2 fail‑safe
Large water pipelines → ABB Butterfly Valves + TZIDC‑200
Pharmaceutical industry → Yokogawa Diaphragm Valves + YVP210
